“…Most cases of congenital retinal macrovessel are found incidentally with no impact on visual acuity suggesting a possible underestimation of its prevalence. Rarely, it may be found in conjunction with vitreous hemorrhage, foveal cyst, serous retinal detachment, branch retinal artery occlusion, macroaneurysm, telangiectasia, macular hemorrhage, or cavernous hemangioma [4][5][6][7][8][9][10][11][12]. The occurrence of the aforementioned associations can result in the deterioration of visual function.…”

“…Later, it was classified as a form of arteriovenous malformation of the retina by Archer et al [3]. This finding, while commonly incidental, has been seen in association with other pathologies such as branch retinal artery occlusion, macroaneurysm, telangiectasia, macular hemorrhage, and cavernous hemangioma [4][5][6][7][8]. More recently, an association with venous anomalies of the central nervous system has been proposed [9].…”

Congenital retinal macrovessel (CRM) is a congenital anomaly where an aberrant vessel supplies both the macula on either side of the horizontal raphe. It is usually an incidental finding but may be associated with other retinal findings that may impact vision. We present an unusual case of bilateral congenital retinal macrovessel in a 40-year-old patient. The patient presented to the ophthalmology clinic for diabetic retinopathy screening and had no visual complaints. The patient underwent a complete ophthalmological examination including fundus imaging, fundus fluorescein angiography, and optical coherence tomography (OCT) imaging. Dilated fundus examination showed bilateral hypertensive retinopathy with optic disc collateral vessels and congenital retinal macrovessels. The multimodal imaging techniques that were used to confirm the finding indicated that the vessel is arterial.

“…Congenital retinal macrovessels mostly affect visual acuity because of the development of macular edema and retinal ischemia. 2,[12][13][14][15] The edema is generally secondary to a blood-retinal barrier alteration occurring in correspondence of the dilated and tortuous vessels, and it frequently resolves spontaneously, unlike the ischemic and neovascular complications typically leading to hemorrhages or persistent damage to retinal tissues. In our case, the cystoid macular edema was due to the presence of an abnormal vascular complex connecting the CRM to the normal retinal vasculature and the intraretinal cysts resolved without any treatment.…”

Purpose: To describe a case of congenital retinal macrovessel complicated by cystoid macular edema associated with contralateral myelinated retinal nerve fibers and retinal vascular abnormalities studied with optical coherence tomography angiography (OCTA).Methods: Case report.Results: A healthy 25-year-old woman with decreased vision in her right eye was found to have a congenital retinal venous macrovessel in the macula associated with cystoid edema. In the contralateral amblyopic eye, the examination revealed a tuft of myelinated retinal nerve fibers along the superotemporal vascular arcade associated with superficial vascular abnormalities. A complete multi-imaging examination was obtained, including fundus color photography, fluorescein angiography, indocyanine green angiography, optical coherence tomography (OCT), and optical coherence tomography angiography. At 1-week follow-up, the optical coherence tomography displayed spontaneous resolution of the edema that remained stable at consecutive 1-month follow-up.Conclusion: Congenital retinal macrovessels can be associated with other ocular developmental anomalies. Vascular complications can occur, leading to macular edema and retinal ischemia. Optical coherence tomography angiography can be useful for the diagnosis and follow-up of this condition.

“…Because the majority of sufferers are asymptomatic, congenital retinal macrovessel is usually discovered unexpectedly on physical examinations or in patients with other ophthalmic diseases. In many studies and in normal eyes [6], partial congenital retinal macrovessel can be accompanied by branch retinal artery occlusion [7], retinal deep capillary ischaemia [8], macular retinal cavernous haemangioma [9], retinal arteriolar macroaneurysm [10,11], retinal peripheral telangiectasia [12], vitreous haemorrhage [13], retinal detachment [14], and even venous malformations of the brain [15]. Archer suggested that retinal arteriovenous communications could be divided into three groups [16].…”

Background: The traditional view is that there are no vessels in the foveal avascular zone. The two cases we report show microvessels crossing the foveal avascular zone. Case presentation: A man and a woman, both 25 years old, were both incidentally found on optical coherence tomography angiography (OCTA) to have unilateral aberrant microvessels crossing the foveal avascular zone in their left eyes. Visual acuity was preserved in both patients. The vessel density (VD) and perfusion density (PD) of the eyes with the aberrant microvessels were all higher than those of the contralateral eyes. Nevertheless, measurements of foveal avascular zone (FAZ) dimensions, including its area, perimeter and circularity, were smaller in the left eyes than in the right eyes. No complications were recorded. Conclusions: To date, aberrant microvessels crossing the foveal avascular zone have not been found to impair visual function. OCTA is a non-invasive and quick method that does not require dilation or the use of fluorescein dye. It is a reliable tool for the detection of aberrant microvessels crossing the foveal avascular zone.
